Abstract

Procédé destiné à ralentir la vitesse de prise d'un ciment au phosphate de magnésium, consistant à ajouter une base appropriée à un mélange aqueux non curé ou partiellement curé du ciment au phosphate de magnésium en quantité suffisante pour élever le pH et réduire au minimum la dissolution MgO/Mg(OH)2. Les ciments au phosphate de magnésium appropriés incluent les ciments au phosphate ammoniacomagnésien et les ciments au phosphate de potassium-magnésium.
